Abstract (en)

The disclosure is related to a method for guiding a user device (10) to establish connection among WLAN access points (AP1, AP2, AP3), and a system thereof. The method is adapted to a WLAN having at least two APs. A master AP is defined. The master AP obtains every AP's signal status of a connection with a user device (10), and its network status. The master AP performs a comprehensive judgment of a communication quality for every AP. Thus, the master AP can determine if the user device (10)'s connection is to be switched to the next AP from the original connection according to assessment of the communication quality. The system allows the network system to perform a hand-off process for the user device (10) in a shortest time once a next AP is found. The problem to be solved by the system is to avoid poor connection quality or disconnection when the user device (10) moves within the WLAN.
